Preheat the oven to 500 F
Disolve the yeast in the water and set it aside. Next, combine the flour and salt (and the herbs and garlic powder if desired). Pour the yeast water into the flour mixture and stir them together. Knead the dough until it's elastic then divide it in half.
This next part is super smart, I discovered it from a website and it works so well. It helps the pizza crust to be super thin. Here it is: Roll the crust out on a piece of parchment paper. The dough sticks to the paper, helping it to stay stretched out and thin when it's uncooked. But as it cooks, the dough releases from the parchment paper. It's so simple but it really makes good crust!
Next, put all the toppings on the pizzas, except for the cheese, and place them (with the parchment paper) onto cookie sheets and into the oven. Bake them for 5 minutes, rotate them, then bake them again for 5 more minutes. After that, add the cheese and put them back in the oven for 10+ minutes, until the crust is golden (or close to golden).

This is one of the best recipes for thin crust pizza that I know of...mmmm...enjoy! :)
